CALENDER.

SPECIFICATION forming part of Letters Patent No. 242,760,,dated June 14, 1881.

Application filed November 5, 1880. (No model.) 4 Patented in France October 11, 1880. I i

To all whom it may concern Be it known that I, ANTOINE J ULIEN Dn- BLON, of Lille, in the Republic of France, have invented anew Calender with three Cylinders, for glazing and pressing all kinds of paper, (for which I have received Letters Patent of France for fifteenyears, dated October 11, 1880,) of which thefollowing is a specification.

The drawings represent the machine for glazing and smoothing paper in an end view, partly in section, by Figure 1, and in a face view, partly in section, by Fig. 2. Fig. 3 is a diagram showing the relative positions of rollers a, b, c, and cl.

Until now the calender from any system whatever has been applied exclusively for calendering press stuffs and tissues.

The calender comprises three cylinders, a, b,

- and 0. Two of these, a and b, have their shafts on the same horizontal plane, and the upper cylinder, 0, is placed between and above the other two.' The cylinders a and b are oscillated mechanically to and fro. Their shafts a and b join in the same motion to and fro, and are hung in fixed cushions. The upper cylinder, 0, has the same oscillating motion right to left and left to right, but it can be moved up or down, as desired. For this purpose the ends of'the shaft 0 can be adjusted in cushions which can slide up or down.

Between the cylinders or rollers a, b, and c, I place the paper 'to be glazed and pressed. This paper is rolled on a bobbin or mandrel, d. The cylinder 0 has to be. lowered for pressing the paper, and it contributes thus,with the cylinders a and b, to the glazing and pressing of the paper. When operated in that way the paper is economically glazed, it acquiresafiner appearance, and is more consistent. The printing subsequently applied is remarkably neat. In case the glazingis made after print the letters are very shining.

In order to calender paper it can be rolled around the mandrel or maintained upon it by bands of linen rolled with it at the same time, and receiving also the glazing action.

The cylinders or rollers 66,1), and 0, and even the mandrel 01, may be heated, if desired.

The three cylinders a, I), and 0, between which is placed the roll of paper, ad, to be glazed, are mounted on the shafts a b 0, as shown in Fig. l.

The lower cylinders, a b, have their shafts a b turning in fixed bearings that hang in the frame B of the machine. The upper cylinder, c, is the pressing-cylinder. It can rise or be lowered at will. the bearings 12, which are adjustable vertically in the frame.

To move the bearings I use two pulleys, q q, over which pass two belts endowed with opposite movements. These belts are bent by means of stretchers, so that it is easy to set in motion one or the other of these pulleys, and consequently to turn the shaft on which they are hung to one side or to the other. Upon the shaft of the said pulleys is fixed the pinion r, engaging with a conical toothed wheel, 8, which, in turn, transmits the movement to the toothed wheel '0 by the pinion u. The shaft 00' of the wheel '0 is threaded to allow this wheel to rise and descend in the frame B,which serves it as a screw-hole. The lower extremity of this shaft wforms part of one of the bearings 10. The same disposition is repeated on the other side of the machine for the second bearing 1?, and this disposition receives the movement of the first by the intermediary toothed wheel y.

(Shown in Fig. 2.) This cog-wheel y, having to follow the wheels 1) 'v, has a threaded hub and is fitted upon the screw 2.

The cylinders a, b, and c are moved to glaze the rollof paper a by a partial rotation from right to left and from left to right, and so on until the work is completed. This oscillating movement is obtained in'the following man ner: On alower horizontal axis, 0 are mounted three pulleys, cl 62 61 The pulley d alone is fixed upon the shaft. With the pulley d is cast a cone pinion, e, which meshes into the toothed wheel f and turns it when the transmitting belt goes around the pulley d", above mentioned. When that belt is on the pulley d the shaft 0 is put in rotation, and as it carries a cone-pinion, 0, this shaft also causes the wheel f to turn. The shaft of the wheel f supports a loose toothed wheel, g, and also a pinion, h. The pinion h engages with a large toothed wheel, 6, loose on the shaft 11 of the cylinder b. Behind the wheel i, and making a.solid body with it, is the pinion j, which engages with a wheel, it, set upon the shaft to of the second lower cylinder, a. On the same axis a of cyl- The shaft 0 turns in.

inder a is also fixed a cog-wheel, l, which governs the four wheels m, n, g, and 0, of the same diameter as itself. The cogs m and gare loose on their shaft, and intermediary between the governing-wheel land the two others, n and 0, that are on the shafts b and 0 of the cylinders b and 0, respectively. This transmission gives the same degree of movement to the three cylinders a b ca movement necessary for perfect glazing.

To give to the rotary movement of the cylinders a b c the go-and-come or oscillating movements desired, the belt displaces itself from the pulley d onto d automatically. A hook, t, fiXed upon the cog-wheel It, strikes a lever which governs arod, to make the belt slide first to the right, then to theleft, and so carry the belt from one pulley upon the other. When that belt is on the pulley d the machine is at rest.

The intermediary cog-wheel m, between 1 and n, is mounted on a lever, 20, which can be moved between 10 and c. It can thus rise and descend without interrupting the movement.

The paper to be glazed, rolled on a block,

d, of wood or metal, is introduced between the cylinders a b 0 while the cylinder 0 is raised. The cylinder 0 is then lowered. By the combination of the upper cogs, r u v 3 one gives the desired pressure, and then the machine is put into motion by moving the belt from the loose pulley 11 upon pulley d or d The change in direction of movement is then efi'ected automatically by the act of the hook t.

I claim- In a glazing or calendering apparatus, the combination of two oscillating parallel rollers, a and I), placed in line horizontally with an upper vertically-adjustable oscillating roller, 0, and with the interposed paper-carrying roller d, and with mechanism for oscillating said rollers under pressure, substantially as herein shown and described.

The foregoing specification of my invention signed by me this 12th day of October, 1880.
